Flat middle plate scraper conveyor head

Abstract

The invention discloses a flat middle plate scraper conveyor head. The flat middle plate scraper conveyor head comprises a head frame, a transition groove and a middle groove, wherein the head frame, the transition groove and the middle groove are connected in sequence. The middle groove is formed in the surface of a working face base plate. One end of the transition groove is arranged on the surface of the working face base plate. The other end of the transition groove extends out of the working face base plate and is connected with the head frame. The head frame is arranged below the horizontal plane of the working face base plate. A tongue plate assembly is arranged in the head frame. An intra-groove plate is arranged in the middle groove in the length direction of the middle groove. The tongue plate assembly is horizontally connected with the intra-groove plate. According to the flat middle plate scraper conveyor head, the head frame is located below the horizontal plane of the working face base plate, the tongue plate assembly in the head frame is horizontally connected with the intra-groove plate in the middle groove, and thus the flat middle plate scraper conveyor head can be adapted to the environment that the space of a thin and middle fully-mechanized coal mining working face is narrow; in addition, a middle plate is free of elevation angle, the situation that a middle plate of an existing scraper conveyor needs to climb is avoided, and abrasion caused by the elevation angle of the middle plate is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of industrial and mining equipment, in particular to a head of a flat plate scraper machine. Background technique [0002] With the development of China's industrial and mining technology, more and more industrial and mining equipment has been widely used. [0003] Taking the commonly used scraper machine as an example, the scraper machine is a continuous transportation equipment that conveys bulk materials by means of a moving scraper chain in a closed rectangular section shell. There are many types of scraper machines, such as double chains in the middle and double chains in the side. [0004] At present, the scraper machine of the double-chain scraper conveyor is used in the thin and medium coal seam working face. Since the old scraper machine is arranged in the form of the scraper machine head, middle part and tail on the fully mechanized mining face, In order to be able to place power parts such as mo...

AI Technical Summary

Problems solved by technology

[0004] At present, the scraper machine of the double-chain scraper conveyor is used in the thin and medium coal seam working face. Since the old scraper machine is arranged in the form of the scraper machine head, middle part and tail on the fully mechanized mining face, In order to be able to place power parts such as motors and reducers, the height of the head frame is much higher than the height of the middle slot, resulting in the structure of the head frame mostly being that the middle plate of the head frame of the scraper machine has a rising angle (generally less than 11 °), resulting in excessive wear of the middle plate in the head of the scraper machine
